Video memory page size -125 Kbytes. The monitor works with a 16 color palette. What is the screen resolution.

V = K * I,
where V is the information volume of the picture (file), K is the total number of points in the picture or the resolution of the monitor, I is the color depth. That is, K = V: l
1 kb = 1024 bytes
1 byte = 8 bits
Follows
1 kb = 1024 * 8 = 8192 bits
125kb = 8192 * 125 = 1024000 bits
K: 1024000: 16 = 64000
Based on the data received, there is an answer: the resolution of the monitor is 64000 pixels
